food safe waterproof fabric

[kellid]

does anyone know of a safe waterproof fabric that i can make reusable food pouches out of?

As far as I've read, there aren't any that have been deemed food-safe. Coated nylons have chemicals in them that are unsafe to ingest and the manufacturer of PUL states on their website that it hasn't been tested for food safety; the waterproof laminate is polyurethane.

Ziplock bags are FDA approved for food safety, I've seen a few sandwich wraps made with a layer of woven cotton print and a cut-up Ziplock sewn inside. One blog I saw had been using the wrap made this way for over a year and it was still functional. For little snack pouches I've been considering using a heavier natural fabric by itself. It wouldn't be waterproof but I guess carrots, grapes and apple slices would be all right.

thanks. that's kinda what i concluded, and even the ziplocks leach in certain temps, not that i would use them that way. i like the heavy fabric idea. i also might try felted wool........see how that goes. thanks for the reply!
